Kristen Stewart On Reuniting With Robert Pattinson For 'New Moon': 'It Was Easy'

"We're both pretty instinctual, impulsive actors," she explained. "We don't really hash things over, over and over because we both know our characters very well."

In fact, the two are so well acquainted with lovesick Bella and melancholy Edward, that it was as if no time had passed between the filming of "Twilight" and its sequel. "It was pretty easy to step back into the project," Kristen said. "Once you play someone, it's a strange thing, you don't forget who they are." It's also doesn't hurt to have a costar you enjoy working with. "We work together well," she added. "So it was easy."
